SockThread is an implementation of multi-threaded sockets. It is has a built-in echo server for telnet connections. It was written with standard native C/C++ libraries. C++ classes std::thread and C socket APIs <sys/socket.h> were used.

QuiteSleep is an Android application that controls which people can interrupt your sleep, or any other activity defined by start and end times. In addition to muting calls, it can send an SMS and email with predefined text to advise callers that you are sleeping or busy.

WikiPBX is a PBX Web interface for FreeSWITCH. Multiple "accounts" are supported per server instance: each account is effectively a completely independent PBX. Configuration is layered so that XML files go on top of what is stored in the database. This allows you to use a database, but stays out of your way if you choose to use flat files. Extensions, SIP endpoints, and gateways can be configured via a Web interface. Live calls can be viewed, hanged up, and transferred. Call history (CDR records) can be viewed over the Web interface. There is a Web interface for managing IVRs. "Sound clips" can be easily recorded for use in dialplan or IVRs. Audio or text-to-speech can be injected into live calls.

Callstats collects and displays call statistics for Siemens HiPath OpenOffice ME in a pretty Web interface. It may work with other Siemens HiPath devices (probably Hipath 3000). With some modifications, it could be adapted to your own system. It has 3 parts: -tcp->text log (via netlog); text log->sqlite database (PHP script); and a Web interface to the SQLite database (PHP). It has been tested without problems in a 50-user installation fulltime since 2009.
